KARA. (4141 Merrill) July. 1905. Mindanao, Davao (540 Copeland) March, 
1904; (100 DeVore tG Hoover) April, 1903. 
Tropics of both hemispheres. 
Perhaps only a variety of Setaria, glauca, distinguished from the typical state 
of that specie.s, especially in the decidedly smaller spikelots.

street, introduced. 
(4) Setaria laxa Merrill, sp. nov. 
Ciilnns debilibiis, erectis, giabris, ramosis, at 1 m. altis; vagiiiis quam 
internodiis imilto brevioribus, glaliris vel sparse pilosis, margine siirsiim 
ciliato-pilosis ; laminis linearibus vel angiiste-lanceolatis, membranaceis, 
7-16 cm. longis; paiiiciilis laxis, elongato-pyramidatis, ad 20 cm. longis, 
paucifloris, ramis ramulisque iiiterdnm jtedicellis in setam pi’odnctis, seta 
scabra, 2-4 mm. longa; spicnlis pancis, solitariis vel binis, giabris, 2-2.2 
mm. longis. 
A slender, erect branched, nearly glabrous grass about 1 m. high, the 
culms 1.5 to 2 mm. thick, glabrous; nodes glabrous. Sheaths much 
shorter than the internodes, glabrous or slightly pilose, the margins 
above ciliate-pilose ; lignle ciliate; blades linear or narrowly lanceolate, 
membranaceous, acuminate, 7 to 16 cm. long, 3 to 5 mm. wide, glabrous 
or lieneath along the nerves with few long white hairs, the margins and 
nerves scabrous. Panicles lax, elongate or elongate-pyramidal, erect, 
about 20 cm. long, the branches slender, erect-spreading, about 8 cm. 
long, few-flowered, scabrous, the branches, branehlets, and sometimes the 
pedicels produced into a 2 to 4 mm. long scabrous awn. Spikelets few, 
purplish, solitary or in pairs, glabrous, narrowly ovate, acute, 2 to 2.2 
mm. long, the first glume 3-nerved, ovate, acute, 0.6 mm. long; second 
glume 5-nerved, ovate, acute, 1.4 mm. long; third glume 5-nerved, 2 mm. 
long; flowering glume 2 mm. long, narrowly ovate, acute, minutely 
rugose. 
Luzon, Province of Laguna, Los Banos (Hallier) December, 1903. 
A species characterized ly its lax habit and panicle, narrow leaves, and com- 
paratively few spikelets. The panicle branches are slender and branched from 
the base, usually solitary, alteniate. Perhaps as ilear Panicum § Ptycophyllum 
as Setaria, hut the narrow leaves are not at all plicate and the pedicels usually, 
hut not always, end in a single bristle subtending the spikelet. No. 21157 j3 
Koorders from Java is very nearly the same, hut in that specimen the leaves aie 
tuherculate hispid or pilose. 
DOUBTFUL AND EXCLUDED SPECIES. 
Setaria macrostaciiya H. B. K. ; F.-Vill. Nov. App. (1883) 312. 
An American species to which some Australian specimens have been referred. 
Not to be expected in the Philippines.
